BACKGROUND Technical Field

The present disclosure relates generally to a boom mower. More particularly, the present disclosure relates to a boom mower attachment and a method of use thereof, where the boom mower attachment includes a cutting mechanism that is moved in a first movement, a second movement, and a third movement by only using two motions of a single control.

Background Information

Boom mowers may be attached to landscaping utility vehicles and be utilized to mow and/or cut vegetation such as grasses, shrubs, hedges, and the like. Frequently, the boom mower is mounted to a rear end of the vehicle and is towed behind the vehicle. This arrangement may make it difficult for the operator to monitor the vegetation that is being mowed or cut while driving the tractor forward. In other instances, the boom mower may be mounted to a front end of the vehicle, such as a tractor of around 100 HP or less. Boom mowers are frequently difficult to remove from the vehicle and this limits the use of the vehicle for other purposes. In addition to these issues, previously known boom mowers have had complex operator controls and a limited cutting range.

FIG. 20 depicts, as hydraulic fluid moves through auxiliary hydraulic circuit line 37 a, which is in operative communication with the fourth hydraulic piston and cylinder device 260, the piston 266 is drawn out of the cylinder 264. The linear movement of the piston 266 out of the cylinder 264 is indicated by arrow G (FIG. 21). The linear movement of the piston 266 causes a separation between the first link member 62 on one hand, and with the third link member 66 and the fourth link member 68 on the other hand, which in turn, causes the second link member 64 to rotate about the third pivot axis X3. The separation causes the first link member 62 to exert a pulling force in a direction shown by arrow H (FIG. 21) on the second link member 64 which rotates the second link member 64 about the third pivot axis X3 in a direction shown by arrow I (FIG. 21).

FIG. 22, FIG. 23A and FIG. 23B depict movement of the first hydraulic lever 280 in a direction indicated by arrow J (FIG. 22), which is the same direction indicated by arrow A and arrow D, when the button 280 is not depressed and the switch 281 b is activated by pressing the switch in a direction indicated by arrow K (FIG. 22), or in the “on” position, and the alert mechanism 286 is activated, which causes movement of the cutting mechanism 16 in the third movement, which is in a direction shown by arrow L (FIG. 22 and FIG. 23B), via hydraulic oil diverter valve 35 of the hydraulic system 33 of the tractor 32 diverting hydraulic fluid through auxiliary hydraulic circuit line 37 c.

FIG. 23A and FIG. 23B depict, as hydraulic fluid moves through auxiliary hydraulic circuit line 37 c, which is in operative communication with the first hydraulic piston and cylinder device 186, the piston 206 is drawn into the cylinder 204. The linear movement of the piston 206 into the cylinder 204 is indicated by arrow M (FIG. 23A). The linear movement of the piston 266 causes the cutting mechanism 16 to rotate about the fourth pivot axis X4 in a direction shown by arrow L (FIG. 23B). More particularly, the linear movement of the piston 266 causes the first sprocket 214 to rotate about the first pivot axis X1 in a clockwise direction, the second sprocket 216, to rotate about the fifth pivot axis X5 in a clockwise direction, the third sprocket 218 to rotate about the fifth pivot axis X5 in a clockwise direction, the fourth sprocket 220 to rotate about the tenth pivot axis X10 in a clockwise direction, and the sixth sprocket 224 to rotate the fourth pivot axis X4 in a clockwise direction. Likewise, the first chain 228 rotates in a clockwise direction about the first sprocket 214 and the second sprocket 216, the second chain rotates in a clockwise direction about the third sprocket 218 and the fourth sprocket 220, and the third chain 232 rotates in a clockwise direction about the fifth sprocket 222 and the sixth sprocket 224. Since the housing 106 of the cutting mechanism 16 is connected to the fourth pivot shaft 94, the cutting mechanism 16 rotates in a clockwise direction as shown by arrow L (23B). As such, an operator (not shown) sets a selectively adjustable rotational orientation of the cutting mechanism 16 by moving the implement 16 in the third movement. The selectively adjustable rotational orientation of the cutting mechanism 16 remains substantially fixed when the cutting mechanism 16 moves in response to the first movement or second movement as more fully described below. In one particular embodiment, the selectively adjustable rotational orientation of the cutting mechanism 16 includes a range of motion of at least approximately ninety degrees; however, the range of motion may be any suitable range of motion. It is to be understood that the cutting mechanism 16 may rotate in a counterclockwise direction in a similar manner as described above in the reverse direction. In another particular embodiment, cutting mechanism 16 may further include a folding mechanism, such as a latch. Unlatching the folding mechanism allows the cutting mechanism to rotate freely on the fourth pivot shaft 94 about the fourth pivot axis X4 which allows the cutting mechanism 16 to be rotated in the counterclockwise direction such that the cutting plane CP is substantially horizontal relative to the ground G. When the cutting mechanism 16 is in this position, the latch may be reengaged to lock the cutting mechanism 16 in that position, which may aid, among other things, shipment of the boom mower 10 to purchasers of the boom mower 10.

Although the first movement, the second movement, and the third movement have been described as being certain directional movements, it is to be entirely understood that the first movement, the second movement, and the third movement can be other directional movements, depending on the context. Thus, a first movement as discussed earlier herein could be termed a second movement or third movement, a second movement could be termed a first or third movement, and, similarly, a third movement could be termed a first or second movement. In other words, if the first movement has been described herein as a generally vertical movement and the second movement has been described herein as a generally lateral movement, those particular directions (vertical and lateral) may be associated with other names; i.e., the generally lateral movement may be called a first movement and the generally vertical movement may be called a second movement.

Now that the procedures and operations for translating or moving the cutting mechanism 16 in at least a first movement, a second movement, and a third movement have been described, the operation of the cutting mechanism 16 will be described. The motor 114 drives the drive shaft 116 a, the end shaft 116 b, the first crankshaft 118, the second crankshaft 120, the first crankshaft plate 122, the second crankshaft plate 124, the third crankshaft plate 126, the first crankshaft rod 128, and the second crankshaft rod 130. The first end 128 a of the first crankshaft rod 128 and the first crankshaft 118 rotate in a path of rotation 118 b about the sixth pivot axis X6. A diameter of the path of rotation 118 b defines a first reciprocal stroke distance S1 (FIG. 17). The first end 130 a of the second crankshaft rod 130 and the second crankshaft 120 rotate in a path of rotation 120 b about the sixth pivot axis X6. A diameter of the path of rotation 120 b defines a second reciprocal stroke distance S2 (FIG. 16).

The first blade rocker arm 154 and the second blade rocker arm 156 are connected to the second crankshaft rod 130 via the second blade assembly shaft 142 proximate the bottom 154 b of the first blade rocker arm 154 and the bottom 156 b of the second blade rocker arm 156. The first blade rocker arm 154 and the second blade rocker arm 156 are connected to the blade plate 148 via the third blade assembly shaft 144. The blade plate 148 extends longitudinally within the space 138 defined by the main frame 132, the top cover 134, and the bottom cover 136. The blade plate 148 is connected to the plurality of blades 150 via the plurality of fastening mechanisms 152. The drive assembly 108 reciprocates at least one blade of the plurality of blades 150 or at least one guard of the plurality of guards 170. More particularly, the movement of the first crankshaft rod 128 causes the blades 150 to move in a direction indicated by arrow N (FIG. 16) in a reciprocating manner covering the stroke distance S2. The first guard rocker arm 174 and the second guard rocker arm 176 are connected to the first crankshaft rod 128 via the second guard assembly shaft 162 proximate the bottom 174 b of the first guard rocker arm 174 and the bottom 176 b of the second guard rocker arm 176. The first guard rocker arm 174 and the second guard rocker arm 176 are connected to the guard plate 168 via the third guard assembly shaft 164. The guard plate 168 extends longitudinally within the space 138 defined by the main frame 132, the top cover 134, and the bottom cover 136. The guard plate 168 is connected to the plurality of guards 170 via the plurality of fastening mechanisms 172. The movement of the second crankshaft rod 130 causes the guards 170 to move in a direction indicated by arrow O (FIG. 17) in a reciprocating manner covering the second stroke distance S1. As such, the blades 150 and the guards 170 both move in a reciprocating manner and since the blades 150 have a different mass relative to the guards 170, the stroke distances S1 and S2 are optimized to reduce translation of vibration from the cutting mechanism 16 to the frame 12 of the boom mower 10 and, in turn, to the tractor 32. The reciprocating movement of the blades 150 and the guards 170 cause a shearing force along a cutting plane “CP”. In one example, the cutting plane “CP” has rotational range of at least approximately one hundred thirty five degrees. In one example, the rotational range of the cutting plane “CP” is between approximately ninety degrees relative to horizontal and negative forty-five degrees below horizontal. In one example, a cutting width “CW” of the cutting plane is approximately thirty-nine inches.

As described above, the cutting mechanism 16 is moveable in the first movement, the second movement, and the third movement. The first movement, the second movement, and the third movement of the cutting mechanism 16 allow the cutting mechanism 16 to move through a range of positions. For example, and not meant as a limitation, when the cutting mechanism 16 has a rotational orientation that is ninety degrees relative to horizontal, the cutting plane “CP” can reach a vertical height equal to at least approximately one hundred forty-two inches from the ground “G”.

In another non-limiting example, when the cutting mechanism has a rotational orientation that is zero degrees relative to horizontal, the cutting plane “CP” can reach a vertical height equal to approximately eighty two inches from the ground “G”. In another non-limiting example, when the cutting mechanism 16 has a rotational orientation of zero degrees relative to horizontal, the cutting plane “CP” can reach a transverse horizontal distance of at least approximately one hundred fifteen inches from an outside portion of the at least one ground engaging wheel 34 of the tractor 32. One of the benefits of being able to move the cutting mechanism 16 in the first movement, the second movement, and the third movement, is that the cutting mechanism 16 can be utilized to mow and/or maintain vegetation along steep ditches, under fences and guardrails, along ponds, lakes, and streams, along trails, pathways or roadways, or any other suitable location.

In accordance with one aspect of the present disclosure, the boom mower 10 in combination with the tractor 32 may form an implement control system 300. The implement control system 300 may include a control, which may be the first hydraulic lever 280, at least one function switching mechanism, which may be the button 281 a and/or the switch 281 b, and an implement, which may be the cutting mechanism 16.

The first hydraulic lever 280 may indirectly move the implement 16 in a first mode, a second mode, and a third mode by only using two motions of the first hydraulic lever 280. The control motion in the first mode is associated with a first movement of the implement 16, the control motion in the second mode is associated with a second movement of the implement 16, and the control motion in the third mode is associated with a third movement of the implement 16.

The at least one function switching mechanism 281 a and 281 b allow the first hydraulic lever 280 to move the implement 16 between the second mode, and the third mode. The first hydraulic lever 280 may be movable between a first position and a second position. In one example, activating the button 281 a allows the first hydraulic lever 280 to cause the implement 16 to move in one or more of the (i) the second mode; and (ii) the third mode. In another example, activating the switch 281 b allows the first hydraulic lever 280 to cause the implement 16 to move in one or more of (i) the second mode; and (ii) the third mode.

The implement control system 300 may further include an alert mechanism 286 that indicates when the first hydraulic lever 280 is operating in one or more of (i) the second mode; and (ii) the third mode. In one example, the alert mechanism 286 is an indicator light on the implement that is by an operator while controlling the control; wherein the indicator light is illuminated to indicate to the operator that the control is operating in one or more of (i) the second mode; and (ii) the third mode.

The implement control system 300 may further include a first end and a second end defining a longitudinal direction therebetween, a first side and a second side defining a transverse direction therebetween, a top and a bottom defining a vertical direction therebetween, and a longitudinal center axis X_(C), which, in one example, may be the first end 20, second end 22, first side 24, second side 26, top 28, bottom 30 and longitudinal center axis X_(C) of the boom mower 10.

In one example, the first movement associated with the first mode is a generally vertical movement relative to the longitudinal center axis X_(C), the second movement associated with the second mode is a generally transverse movement relative to the longitudinal center axis X_(C), and the third movement associated with the third mode is a rotational movement about a rotational axis that is offset parallel to the longitudinal center axis X_(C). In one example, a rotational orientation of the implement 16 relative to the rotational axis may be selected or set by moving the implement 16 in the third mode. The rotational orientation of the implement remains substantially fixed, i.e., substantially unchanged, when the implement moves in one or more of the (i) the first mode; and (ii) the second mode. As such, as the implement mechanism 16 moves in the transverse direction, the implement from the ground “G”.

FIG. 24 depicts an exemplary method or process in accordance with one aspect of the present disclosure and is generally referred to as 2400. The method 2400 includes moving a control, which may be the first hydraulic lever 280, of an implement control system 300 between a first position and a second position to cause an implement 16 to move in a first movement, which is generally shown at 2402. The method 2400 may include switching, via at least one function switching mechanism 281 a, 281 b, a function of the first hydraulic lever 280 from the first mode to at least one of (i) a second mode; and (ii) a third mode, which is shown generally at 2404. The method 2400 may include moving the first hydraulic lever 280 between the first position and the second position in the at least one of (i) the second mode; and (ii) the third mode, which is shown generally at 2406. In one example, the control movement in the first mode is associated with a first movement of the implement 16, the control movement in the second mode is associated with a second movement of the implement 16, and the control movement in the third mode is associated with a third movement of the implement 16.

In one example, the at least one function switching mechanism 281 is a button 281 a and switching the function of the first hydraulic lever 280 from the first mode to at least one of (i) the second mode; and (ii) the third mode is accomplished by depressing the button 281 a, which is shown generally at 2408.

In another example, the at least one function switching mechanism 281 is a switch 281 b and switching the function of the first hydraulic lever 280 from the first mode to at least one of (i) the second mode; and (ii) the third mode is accomplished by activating the switch 281 b, which is shown generally at 2410.

In another example, the at least one function switching mechanism 281 is a button 281 a and a switch 281 b and switching the function of the first hydraulic lever 280 to the second mode is accomplished by depressing the button 281 a and switching the function of the first hydraulic lever 280 to the third mode is accomplished by activating the switch 281 b, which is shown generally at 2412.

The method 2400 may include indicating, via an alert mechanism 286, when the function of the first hydraulic lever 280 has been switched via the function switching mechanism 281 a, 281 b to at least one of (i) the second mode; and (ii) the third mode, which is shown generally at 2414. In one example, the alert mechanism 286 is an indicator light also denoted 286, and the method 2400 further includes illuminating the indicator light 286 when the function of the first hydraulic lever 280 has been switched via the at least one function switching mechanism 281 a, 281 b to at least one of (i) the second mode; and (ii) the third mode, which is shown generally at 2416.

In one example, the first movement associated with the first mode is a generally vertical movement relative to the longitudinal center axis X_(C), the second movement associated with the second mode is a generally transverse movement relative to the longitudinal center axis X_(C), and the third movement associated with the third mode is a rotational movement about a rotational axis that is offset parallel to the longitudinal center axis X_(C). The rotational orientation of the implement remains substantially fixed when the implement 16 moves in at least one of (i) the first mode; and (ii) the second mode.

While the hydraulic cylinders and pistons have been disclosed herein and illustrated in the figures in a particular orientation, it will be understood that the positions of the cylinders and pistons may be swapped. For example, in FIG. 6 the cylinder 204 is shown engaged with the pivot arm 188 and the piston 206 is shown engaged with the hanger bracket 200. In another example, however, the cylinder 204 may be engaged with the hanger bracket 200 and the piston 206 may be engaged with the pivot arm 188.

Also, various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

The articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper”, “above”, “behind”, “in front of”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”, “lateral”, “transverse”, “longitudinal”, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

Although the terms “first” and “second” may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.

An embodiment is an implementation or example of the present disclosure. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” or “other embodiments,” or the like, are not necessarily all referring to the same embodiments.

If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.

As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical range recited herein is intended to include all sub-ranges subsumed therein.

Additionally, any method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
